Which of the following should be observed with the addition of a catalyst to a chemical reaction?

A. the formation of a new product

B. the consumption of the catalyst

C. the activation energy is lowered

D. the decrease in enthalpy

Correct Answer: C.the activation energy is lowered

A catalyst speeds up a chemical reaction by lowering the activation energy of a reaction. The catalyst is never consumed, nor does it alter the reactants or products. The total enthalpy of the reaction is also not changed from what it would have been without the catalyst. Only the rate at which the reaction occurs and the activation energy is affected. The only answer option that is correct is [C].
